Question 3 -- 220.127.116.11.2.3
Describe the difference between the indications of
a hung start and a wet start.
1. A hung start is indicated by stagnated rpm below
52% and with slowly rising EGT.
2. A wet start is indicated by fuel flow and no EGT rise
within 15 seconds of setting throttle to IDLE.
Question 4 -- 18.104.22.168.2.3
During engine start, you observe a rapidly climbing
EGT that appears likely to exceed the maximum
EGT (550 degrees C). Identify what this indicates
and list three causes.
ANSWER: This indicates a hot start and can be
caused by wind blowing up the tailpipe, starting a hot
engine, or high ambient air temperature.
